METHOD OF MANUFACTURING ELEVATOR LINKS AND A CAST ELEVATOR LINK BLANK FOR USE IN THE METHOD

摘要

A method of making a one-piece elevator link having a shank with an eye at each involving the steps of casting from alloy steel a link blank having an oversize shank portion, forging or swaging the shank portion to reduce its diameter and correspondingly elongate it, and heat treating and drawing the forged or swaged blank to enhance its physical and mechanical properties. The eyes are cast in their final form. The oversize shank portion may be machined to reduce its diameter before it is forged or otherwise hot worked, whereby casting of but one size may be used in the production of elevator links of varying lengths. A cast elevator link blank to be hot worked into an elevator link of final form.
